Tsar Bomba

Tsar Bomba was the Western nickname for the Soviet RDS-220 hydrogen bomb, code name Vanya. It was tested on October 30, 1961, and remains the most powerful human-made explosion in known history. Developed by the Soviet Union, the bomb had a yield of 50-megaton TNT, and a maximum yield of 100-megatons if it were to have included a U-238 tamper, but because only one was built, this theory was never demonstrated.

5. Equivalent to 1,570-times the Combined Energy of the Bombs That Destroyed Hiroshima and Nagasaki

Tsar Bomba

This is equivalent to about 1,570 times the combined energy of the bombs that destroyed Hiroshima and Nagasaki, 10 times the combined energy of all the conventional explosives used in World War II, one quarter of the estimated yield of the 1883 eruption of Krakatoa, and 10% of the combined yield of all nuclear tests to date.

4. Flown to Test Site in Modified Tu-95V Plane

Tsar Bomba

The Tsar Bomba was flown to its test site by a specially modified Tu-95V release plane, flown by Major Andrei Durnovtsev. Taking off from an airfield in the Kola Peninsula, the release plane was accompanied by a Tu-16 observer plane that took air samples and filmed the test. Both aircraft were painted with a special reflective white paint to limit heat damage. Despite this effort, Durnovtsev and his crew were assigned only a 50% chance of surviving the test.

3. Weighed 27-Metric-Tons

Tsar Bomba

The bomb, weighing 27 metric tons, was so large (26-feet long by 6.9-feet in diameter) that the Tu-95V had to have its bomb bay doors and fuselage fuel tanks removed. The bomb was attached to an 800 kilogram parachute, which gave the release and observer planes time to fly about 28-miles away from ground zero. When detonation occurred, the Tu-95V dropped one kilometer in the air because of the shock wave, but was able to land safely.

2. All Buildings Within Sukhoy Nos Test Range Were Destroyed

All buildings in the village of Severny (both wooden and brick), located 34-miles from ground zero within the Sukhoy Nos test range, were destroyed. In districts hundreds of kilometers from ground zero wooden houses were destroyed, stone ones lost their roofs, windows and doors, and radio communications were interrupted for almost one hour.

1. Could Not Be Delivered by ICBM

The weight and size of the Tsar Bomba limited the range and speed of the specially modified bomber carrying it and ruled out its delivery by an intercontinental ballistic missile. Much of its high-yield destructiveness was inefficiently radiated upwards into space. It has been estimated that detonating the original 100-megaton design would have released fallout amounting to about 25% of all fallout emitted since the invention of nuclear weapons.
